I agree Thelk4, except that I used to like Melissa. She was funny on her season of RW. Last night she seemed so mean.
I find it hard to believe that Puck has changed at all although he did seem to hold back pretty well with David. David appeared to be strung out. He was very gaunt looking. He probably left the show to get a fix.
When someone said it would be the Jerry Springer of RW/RR challenges, they weren't kidding!
